Would the look of my neck be considered a lower neck lift failure and can this sometimes happen? Would a revision help? (Photos)

Thank you for your question.  It is difficult to give you a proper opinion without pre-op pictures and an examination in person to determine if those bands are skin or muscle and assess the degree of scar tissue and the quality of the skin.  In facelift or neck lift surgery, there is often a 15% relapse rate of some banding under the chin (assuming that area was smooth initially after the surgery).  This is due to the skin stretching back out to allow you a full range of neck mobility as things heal, and then not having the intrinsic elasticity to fully contract without some buckling as you return your neck to a neutral position or flex it.  
Our skin when we were young is like a fresh elastic band with a lot of stretch and contraction ability.   As we age, it is more like a rubber band left outside in the sun for a few years - the skin loses elasticity and tends to buckle much sooner.  Removing the excess with a face/necklift improves things but cannot restore the natural elasticity of the remaining skin.
It is possible that re-tightening the skin or addressing the platysma muscle (depending which is causing the bands) can improve the contour at a later date.  Other modalities using laser, radio frequency energy or other modalities can also tighten skin and reduce banding.  
I would follow your surgeons advice, see them at 6 months and discuss at that point what the options are to get you the contour you were hoping for.  If they cannot get you there, I would seek another opinion from a well respected board certified Plastic Surgeon in your area.

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in-person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

Thank you for a question.  I saw your results, I am sorry about  them, but I recommend you go back to your doctor because you need a revision to correct your neck.

Thank you for your pictures. You have developed a trust with your initial surgeon and follow through with that doctor is the next best step. Without seeing your initial pictures, it is hard to see how much improvement occurred. Seeing such muscle neck banding so early in your recovery is atypical. Injecting a neurotoxin was a good idea. It should have helped. 
If you have concerns you may want to seek additional consultations with board certified plastic surgeons that are members of ASPS and ASAPS. 
Hope this helps!

A platysmaplasty under local would be so great and easy to undergo and make such a dramatic improvement.  Don't wait any longer . You need it so get it done asap.

Dear S1226,
Thank you for your question. It is difficult to make an accurate assessment and recommendations based on photographs alone. I recommend you continue to seek serial follow-up with your surgeon as you are still healing. If you are at six months to a year out with unimproved issues in the submental area, your surgeon may consider you to be a revision surgery candidate.

Thank you for sharing your excellent question and photographs and I am sorry that your result has not been what you anticipated.  I do think a revision would afford you an improved appearance and it appears that tightening of the central neck, as well as the outer neck will be required to get the best aesthetic, and to remove excess skin.  Hope this helps.

It’s unusual that your central thickening is increasing with time in the area of the platysmaplasty. An examination is needed to see if this is scar tissue which actually is supposed to decrease with time. The inverted y appearance may indicate loss of suture in the area. It’s best to wait as long as possible for revision if this is scar tissue. It’s best to follow with your doctor but don’t waste time with botox.

Its not possible to know how good of a candidate you are for a revision even with your pics, without performing an exam.  My guess however is that a revision would take care of that or at least improve it.  I would have to know a bit more about how your original procedure was performed, but I do see the platysmaplasty scar.  At this point, my advice is to continue regular followup with your original surgeon.  I don't perform revisions until 1 year after the original procedure, but have performed hundreds of facelift revisions over the years.  

Much more information is needed, such as Your age, a full set of facial photographs from all angles, and copy of the operative report to see what was accomplished. From the limited photographs presented, there appears to be platysma muscle cords, residual fat, and excess skin for which a lower face and neck lift will be required.
